e newly appointed Government of a small island, depend on the import of fossil fuels to produce electricity, has the desire to invest in one or two renewable energy technologies. The advantage of the island is the number of different renewable energy potentials. The cost of electricity on the island is $0.39 kWh. 1) Using solar radiation photovoltaic technologies, it was estimated that 500 rooftops, with a total surface area of 456 000 m2 , will be available to install the photovoltaic panels. Assume that the solar panels actually cover 90% of the available surface area. Given, the size of a standard photovoltaic cell is 156 mm by 156 mm and for a silicon photovoltaic cell, each PV cell produces a current of 2.5 A at a voltage of 0.5 V. The average daily irradiance for the island is 185 W/m2 . Assume the initial capacity expenditure evaluated on a year basis of the photovoltaic system, that covers, 90% of the available surface area is US $600 000 and the annual operating cost is US $5 000. Determine, for the photovoltaic system, that cover 90% of the available surface area, (i) the power produced, in kWh, (ii) annual energy produced, (iii) the efficiency of the solar powe

Determine, for the photovoltaic system, that cover 90% of the available surface area,
(i) the power produced, in kWh,
(ii) annual energy produced,
(iii) the efficiency of the solar power,
(iv) levelized cost of electricity (LCOE), and
(v) compare the LCOE value and the cost of electricity, and comment on the capital investment.(only question iv and v are required please dont answer i,ii and iii)
